Abstract :
The South African SAR system (SASAR) has flown a number of repeat pass interferometry flights, and this paper reports on the results achieved to date with the system. The flight geometry, data acquisition and processing are described, and examples of interferograms are shown. This paper also shows simulations of fringe patterns obtained from an interferogram simulator developed in the UCT Radar Remote Sensing Group. The simulated fringes obtained from a DEM are compared to those obtained from the real SAR data
